entropython

A Python module for efficient calculation of Shannon byte entropy based on Rust.

Installation

Just run

pip install entropython

Usage

from entropython import shannon_entropy, metric_entropy

bytes = 'Lorem ipsum dolor sit amet, consetetur sadipscing elitr, sed diam nonumy eirmod tempor invidunt ut labore et dolore magna aliquyam erat, sed diam voluptua.'.encode('utf-8')
print(shannon_entropy(bytes))
print(metric_entropy(bytes))

Build from Source

For building the binary from source, Rust needs to be installed.

Run

cargo build --release
mv target/release/libentropython.so entropython.so # The renaming is necessary for Python to find the module
# Optional: Remove debug symbols from the binary to dramatically reduce its size.
strip entropython.so

The built entropython.so itself has no dependencies.
